The 2025 U.S. State of the Birds report indicates continued decline in North American bird populations, originally revealed by a 2019 Science article. Key findings reveal that a third of American bird species are now classified as high or moderate concern, including alarming rates of decline among grassland and arid-land birds. While waterfowl numbers had previously increased, a recent decline of 20% since 2014 raises concerns. The report emphasizes the need for immediate action to address the accelerating threats faced by various bird populations across regions.
The rapid declines in birds signal the intensifying stressors that wildlife and people are facing, indicating urgent action is needed to conserve these vital populations.
About a third of American birds, or 229 species, are of high or moderate concern due to declining populations and threatening trends that put them at risk.
